Three male amputees from Austria have successfully received robotic hands as a replacement for their injured hands. These men were the first to have doctors perform bionic hand reconstruction on amputees. They all suffered from accidents which damaged the brachial plexus – the bundle of nerve fibers running from the spine to the hand. Doctors initially tried to repair the nerves, but their hands and arms remained paralyzed.

The damaged hands were electively amputated and replaced by prosthetic ones. The elective amputation allows surgeons to plan where the incision will be made and how the prosthesis can graft to the bone for stability. The prosthetic hands are controlled by the patients’ mind using muscle and nerve tr...
